MANUFACTURFCNG COMPANY, OF BELLEVILLE, NEW JERSEY, A COR- MAGHENE FOR POLISHING INSULATED WIRE- srncmicmricn forming part of Letters Patent No. 761,634, dated May 31, 1904. Application filed September 29, 1903. I Serial No. 175,081. (No model.)

To all whom, it may concern: Beit known that we, OLIVER T. HUNGER- FORD and CHARLEs F. Kineonn, citizens of the United States, residing at Belleviile infthe county of Essex andStateof New Jersey, have invented certain new and useful Improvements in.- Machines for Polishing Insulated Wire, of

which the following is a specification.

This invention relates to a machine designed for smoothing, hardening, and polishing the exterior surface of insulated wire.

The object of the invention is t0 provide a simple, smalhcompact, and efiicient machine which can be adjusted while it is in operation.

.The machine shown as embodying the in-- vention .has a pair of tubular spindles supported by bearings mounted 'on a bed. Each spindle has keys that when moved in one .direction lock the spindle to adriving-pulley, also oscillate levers with polishing-blocks so that they will grasp a wire passing through the spindle-and when moved in theopposite direction unlock the spindle from the pulley and open the blocks from the wire. Each set of keys is moved by an angle-lever that is oscillatedby the vertical movement of athreaded adjusting-sleeve, which is provided with a turning-handle.

Figure 1 of the accompanying drawings shows a plan of this machine. Fig. 2 shows aside elevation. Fig. 3 shows a vertical longitudinal-section through one of the spindles on the plane indicated by the dotted line 3 3 I on Fig. 1, and Fig. 4; shows a vertical longitudinal section through the other spindle on %18- plane indicated by. the dotted line 4 4; on

*ig. .1. i i

The tubular spindles 5 are held by bearings formed at the top of blocks 6 on the open bed 7. A pulley 8 is loosely mounted upon each spindle between the bearings, and a collar 9 isfastened on the end of each spindle. In each pulley there are key-slots 10. tises iii the head of each spindle are a pair of levers 1,1, to the outer ends of which polishing-blocks 12 are held by screws 13, that pass In morthe front of. the collar which is attached to the keys engage the inclined rear edges of the hooks on the rear ends of the, levers and so oscillate the levers that the polishing-blocks are openedapart. This movement of the keys also unlocks the pulley and allows it to run loose. When the keys are moved baekwardly, the inclined front edges of the hooks on the rear ends of the levers are engaged by the inclined edges of the front ends-of the keys 'in such manner that the levers are oscillated jand close the blocks toward each other, and

.79?" the key-slots and lock the'p'ulleys and the during backward movement the keys enter spindles together. Each key-collar is engaged by the ends of a yoke 17 on an angle-lever 18, 'which is pivotally mounted upon an arm 19, that projects from the forward spindle-bearing. The upper end of each angle-lever has a yoke 20, the ends of which engage the grooved lower end of a sleeve 21, which has an interior thread that fits the exterior thread 1 of a stud 22, that is screwed into the top of the forward spindle-bearing. Each sleeve,

has a handle 23, by means of which it may be rotated. v When a handle is turned so a sleeve rises, the angle-lever that engages the sleeve through the collar moves the keys backwardly, so that their rear ends will ,look the pulley to the spindle and their forward ends will oscillate ward eachother and against a'piece of wire passing througlf the spindle. The surfaces 24: on the ends of the levers and the surfaces the levers and-bring the polishing-blocks tobular spindle, levers with polishing-blocks car stantially as specified.

25 on the ends of the keys are preferably in- I Y clined, so that the farther the keys'are drawn backward the tighter the polishing-blocks the blocks from each other and from a piece of wire extending through the spindle.

Two lengths of insulated wire can be continuously fed through the spindles of the machine that is illustrated, and the polishingblockscan be closed uponthe wire with the desired degree of pressure while they are rotating rapidly and the wire is being fed. The pressure of the polishing-blocks upon the wire can be regulated without stopping the machine.

The invention claimed is 1. A polishing-maehinehaving a rotatory tu-,

ried by the spindle, a pulley loosely mounted upon the spindle, keys movable longitudinally of the spindle and adapted to oscillate'the levers and lock and unlock the pulley and the spindle, and means for moving the keyswhile the1 spindle is rotating, substantially as specifie 2. A polishing-machine having a rotatory tubular spindle, levers with polishing-blocks carried-by the spindle, a pulley loosely mounted upon the spindle, keys movable longitudinally of the spindle and adapted to oscillate the levers and lock and unlock the pulley and the spindle, a lever adapted to move the keys, and a handle adapted to oscillate the level sub- 3. A polishing-machine having a rotatory tubular spindle, levers with polishing-blocks carried by the spindle, a pulley loosely mounted upon the spindle, keys movable longitudinally of the spindle and adapted to oscillate the levers and to lock and unlock the pulley and the spindle, an angle-lever adapted to move the keys, and a threaded sleeve adapted to escillate the angle-lever, substantially as speci- 4. A polishing-machine having a rotatory tu bular sp indle,levers carried by the spindle,polishing-blocks adjustably attached to the levers, a pulley loosely mounted upon the spin dle, keys movable longitudinally of the spindle and adapted to oscillate the levers and to lock and unlock the pulley and the spindle, an angle-lever adapted to move the keys, and a handle adapted to oscillate the'angle-lever, substantially as specified.

5. A polishing-machine having a rotatory tubular spindle, levers with polishing-blocks car ried by the spindle, a pulley loosely mounted upon the spindle, keys movable longitudinally of the spindle, the forward ends of the keys being adapted to engage with and oscillatc the levers and the rear ends of the keys being adapted to lock and unlock the pulley and the spindle, a collar movable on the spindle and fastened to the keys, an angle-lever adapted to move the collar and a handle adapted to oscilliate the angle-lever, substantially as specifie( 6. A polishing-machine having a bed, rotatory tubular spindles supported by bearings mounted on the bed, levers carried by the spindles, polishing-blocks mounted on the lovers, a pulley loose upon each spindle, keys movable longitudinally of the spindles and adapted to oscillate the levers and lock and unlock the spindles and the pulleys, angle-levers for moving the keys and a handle for oscillating the angle-levers, substantially as specilied.

7. A polishing-machine having a rotatory tubular spindle, levers pivotallymounted upon the spindle, polishing-blocks attached to the levers, keys movable longitudinally of the levers and adapted to engage with and oscillate the levers, and means for moving the keys longitudinally of the spindle, substantially as specified.
